The human eye has capabilites that you'd need a camera more expensive than a LiDAR by a good bit too replicate. No rolling shutter, very low delay, continuous signal processing instead of per-frame, maximum resolution around ~70MP eq. in the center, f/2.8 aperture at a full-frame image size, servo driven active rangefinding, continuous cleaning, etc...

A camera with those features would be around 3000-15000$, and you'd need two.

Also, the human brain can use focus information and stereo phase to deduce 3D structure, which is another ace up its sleeve.

It might very well be the case that reproducing this is more expensive in training, processing and material than LiDAR. In fact, I'd say it's very likely - we're talking loops that need to update hundreds of times a second and data rates in the gigabits, which our brains deal with by doing a lot of processing inside the eye and along the way.
The abstract objects which aren't self-defeating [0] are real in this sense. Of course, note that we can't simply quantify over such objects since there is no universal way to decide whether objects are self-defeating, but it is nonetheless a simple criterion.

> Autocracies seem to be the most efficient form of governance

Efficient in achieving a particular goal, sure, but the wisdom of crowds (and the market) is a thing, too. When the autocracy decides X will be the next big thing, and it isn't, all that efficiency from the previous correct bets gets wiped away by the inefficiency of one wrong dictate from the top.

SoCal is the exception and not the norm as a develop country with enough wealth to afford electric cars while having a non reliable electric grid.

Most of the other countries with unreliable electric grid are not very much into the brand new premium electric cars market.
Guarantee they're breaking some rule for listing Sam and others on their website as "investors". If not, that's super dodgy that Coinbase Ventures allows their portfolio companies to do so.
> "Real" for humans, is whatever we experience directly. Therefore, colour is as real to a blind man as snow to a person who's born in the equator.

This sounds like crazy talk to me. Of course those two things are entirely real.

The fact that we can deduce reality and communicate it to others in a truth-preserving manner is a fundamental underpinning of society. I think it's dangerous to suggest that reality is relative.
If you're an institutional investor in real estate, you can use real estate to generate a nice steady income, via rental. People who aren't parking capital or laundering money tend not to invest in houses to keep them empty.
This is coming in late, but the short answer is "I have no idea".

The slightly longer answer is "I don't know. But once you have the space and equipment and you're sure you can handle everything safely you still need to staff this and build up some institutional knowledge." If you're thinking this far, you should ask why 65nm? Because it's a process node you know a certain microprocessor was built on? It's just a benchmark that's useful for working out your sense of what it costs to do these from scratch?

The cheapest way to get the equipment would be buying out a fab that's shutting down. When I was in undergrad, I got to play in a 5 micron (5000nm) fab on campus because the previous owner of all the equipment gifted it to the university instead of scrapping it. My gut sense is that there's nothing at 65nm that's unprofitable yet, so you're not getting cheap stuff.

(a 6 micron node was commercialized in 1974, this university lab was opened in 1993. 65nm was commercialized in 2005. While Moore's Law held, more or less, through much of 1974-2005, I think we can say that the difficulties and necessary capital investments increased super-linearly over that time. And 20 year old manufacturing tech seems much more useful now than it did in '93. The STM32 family of microcontrollers, a very strong line, is spread over the 132-40nm range of process nodes.)
I don't get it. I've implemented B-trees. The majority of space the used by a B-tree is the data itself. Each N-ary leaf of the tree is a basically a vector of data with maybe some bookkeeping at the ends. The leaves are more than half of the tree.

Sure, you can compress the data. But that depends on the data, completely random data can't be compress. Other data can be. But a point blank 83x space claim seems bizarre - or it's comparing to a very inefficient implementation of a B-tree.

Edit: It seems the 83x claim is a product of the HN submission. I could not find it on the page. But even the page should say something like "a compressed index that allows full speed look-up" (akin to succinct data structures) and then it would make sense.

The hud as you call it is not a safety critical part of the car in Teslas. You can reboot it while driving without effecting the car. The self driving computer is separate and has full redundancy to the point of having two processors running redundant code. There is a reason Tesla’s are consistently rated as the safest cars on the road with low probability of being involved in an accident and lowest probability of injury when an accident does happen.
Tesla is organized functionally. The Infotainment Group did the Console electronics. The SW people there did GUIs and such. So yes between the electronics folks and the app folks 'somebody' didn't consider write cycles. In other Tesla groups, such as Body Controls, and Propulsion -- I can assure you those geeks know such things and plan to deal with funky hardware. The Autopilot group is again separate. There really isn't much crossover. "Systems" is unfortunately an unknown word at Tesla. You know, parts is parts.
> it charges to 100% every time

Ah, I hadn't picked up on this. My BMW i3 has a built-in buffer so what shows as 100% on the dash is actually about 80%, and similarly for 0% (I verified through the raw data).

Doing true "0-100" definitely does not do the battery any favors.
There's no evidence yet (that I'm aware of) which is why experts are very cautious against giving false hope.

But based on past vaccines for other viruses and the way they and the covid vaccines help your body be better prepared to fight the virus, it's a reasonable guess that they may well at least limit spread, perhaps even close to prevent it.

So you're right to point out that it's not a sure thing, but I (admittedly, not an expert, but basing on views of experts) also think it would be more surprising if the vaccines didn't slow spread at all, the bigger question will be to what extent (both with and without current protective tools like masks and social distancing).
It is a more complex and expensive inverter that can operate both isolated from the grid and in sync with it I think because it has to know when to do which and if it is outputting power how can it tell if the system is live because it is grid tied or because it is keeping the system energized itself.

I think they need external signals to tell them which mode to operate in.

Maybe the external system sees the frequency and voltage dropping or lower than normal range and decides to disconnect the load from the grid and opens a breaker and tells the inverter to operate in isolated mode.

When the external system sees the utility power is good again it could tell the inverter to shut off, close the breaker to connect the load to the utility, and then the inverter can go back to grid tie. The outage can be very short unless the load is large motors they don’t like the instantaneous change in phase when switching between different sources that are out of sync.
House price appreciation is a side effect. You can still collect rent. Or have a roof over your head.
Supercharge was built because I had a lot of requests as a developer to deliver the same things over and over again - Basic pages, a simple datastore, authentication, analytics, forms etc.

Yes, there are existing open source packages. But I couldn't find something which combined all of the above seamlessly with dedicated support for clients.

What you see in the "Preview" tab is only the first instalment of what's to come. In the coming days, there will be variations with different data stores, authentication mechanisms, quickstarts for mobile apps etc.

I have had a few sales and many further requests that have filled my backlog and I am working actively on it. The customers are usually early stage devs or students who want to learn how to build such apps.

As a kid, one of my biggest fears were automatic doors. I sort of imagined they would close on me and try to kill me. I am afraid this horror is going to be true at some point of my life. Automation is going to kill me one day.
Clearly, other governments can do it, so there must be a way for the US to do it too.
There are many such boilerplates, but the concept is to have end-to-end integrated UI, datastore, dashboard, auth, analytics etc. and of course with dedicated support
I've come to the conclusion that they don't care about their paid users. It's an ad company that operates at scale, "power users" that require support or expect services not to get randomly turned off only jam up the gears.
Using non standard definitions for words and then saying that everyone else is wrong is a better way to get people to read your blogs though.

How to End Social Media Addiction and Protect Your Mental Health
>inherent in all social networks

Yep. I've been using Fosstodon for a couple months. It's not much different from the others, except that the typical Fosster is at least as tech-focused as HN. Without room for 10-paragraph expositions.

My daily surf starts with topical sites I know will pay off for me from experience. Later I'll quickly scan HN and various subReddit headlines for items of interest. Finally (time allowing) do I drop into xtodon to walk the seashore and see what the waves left.

Some nice days I like to sit and people-watch. Social media's more like mind-watch. Like BBS's did, sometimes the waves leave some useful flotsam. Mostly it's kelp.

AIOS! It analyzes your usage of features in your current operating system, and uses Deep Learning to provide you with source code with just those features as efficiently as possible (uses approximate solutions to NP-complete algorithms), scoured from open source projects meeting your specified license requirements. Paid features include finding the fastest + bug free drivers. For substantially more money you can get a machine-generated proof of theoretical correctness of a component, including Deeply Learned bug fixes. (Not to be confused with AIX, which is still handmade, or with AIX11 which uses convolved neural networks run on the hn-x11-complaints BigData-set to write a custom X11 server that is still remoteable but also Modernly Designed)

The fact that it's mRNA isn't really relevant to how your body fights the virus, it's still the same mechanism.

The traditional way (as used by the Oxford/Astrazenica covid vaccine, and others) is to show the body what the virus looks like by giving it non-harmful bits of protein that look like the bit of the virus the immune system will need to recognise.

The mRNA ones (like Pfizer's or Moderna's) use mRNA code to tell your body to create those harmless proteins, and then the rest is the same - your immune system learns to recognise them, which is good because it will be more likely to recognise the real virus.

The mRNA technique is just moving the "create these harmless things" from the lab to inside the body. It doesn't change how your body fights the virus compared to traditional vaccine methods.

(mRNA vaccines have also been undergoing safety tests for years, these ones for covid are the first approved but not because previous/ongoing ones were shown to be unsafe.)

Because the need for massive, acute production capacity for a specific variation of vaccine is short-lived.

What's the odds that we're going to have another pandemic in the next 10 years that has nRNA vaccine?

There's no need for massive production capacity other than during a global pandemic, and you probably don't know what you need, supply chains etc. until the time of production or thereabouts.

So - the money won't go into building out production capacity for something, when we don't know what that something is, it's constituent parts, or what technologies will be utilized.
I think the OP meant speculative. Most jobs create value, some don't. Some people just have a hard time digesting and wrapping their heads around making money without creating actual value.

American regulations. Because of ITAR, SpaceX cannot legally export any of their development or manufacturing. This means they are, and will always be, subject to all the other American regulation too.

And there is precedent that even if an American company launches their satellite from somewhere that is not the USA, they still have to follow all the American regulation. See FCC and Swarm Technologies over the SpaceBee 1-4 launch.
An apple is an abstraction. It's a combination of chemicals bonded together. Those chemicals are composed of atoms which are bonded together, each of which are composed of electrons, protons, and neutrons. Those particles are composed of quarks, and so on.

An apple is a singular thing because it is useful for us to think of an apple as a singular thing in most contexts. It is not a singular thing when it is more useful to look deeper.

SkyWater bought a primarily 200nm, but 65nm capable fab in Minnesota for 30M in 2017.

https://www.eenewsanalog.com/news/ceo-interview-sonderman-sk...

Granted, it's tooled for 200mm wafers (300mm are the standard right now), but it's still significantly cheaper than expected.

Prices are likely to ramp up really quickly when you get to the 65->45nm jump - that's when Intel started using multiple patterning.
I'm quite surprised intuitionism is not brought into this conversation.

> Intuitionism is a philosophy of mathematics that was introduced by the Dutch mathematician L.E.J. Brouwer (1881–1966). Intuitionism is based on the idea that mathematics is a creation of the mind. The truth of a mathematical statement can only be conceived via a mental construction that proves it to be true, and the communication between mathematicians only serves as a means to create the same mental process in different minds. [^0]

The intuitionistic logic, through Curry-Howard-Lambek correspondence, serves an important role in proof theory and model theory.

Your guess is pretty on the point. TSMC has been jokingly hailed as "The protector of the country" by the Taiwanese media. The chips have military significance for the USA, as it has been trying to avoid China made electronics in all (or most?) equipments.
It's not hard to see the trajectory however. I heard the same types of arguments against digital cameras. Ten years later film cameras barely exist.
It is very helpful to know that this can work.

Insurance companies have unique regulatory requirements specifically because they used to do what Google does now: ghosting paid-up customers. In their case, many insurance companies welcomed regulation to maintain a level playing field. It would otherwise become too easy for some to collect premiums but not pay out obligations, and thereby be able to undercut more honest companies. But for this to work, state Attorneys General need to take enforcement seriously, and resist capture. California's Attorney General is elected, which helps there.
Revenge killings like that are not as frequent at all, even in cases where perpetrator walks free. Maybe you would do it, but majority of people simply don't.

Revenge killing is good movie plot, but not really the reality of western culture nor was for it reality in past.
The reason NZ is temporarily covid-0 is because the government trusted the scientists, and the people mostly trusted the government.

Much of what the NZ govt does would for sure be seen by many Americans as "massive overreach".

The vast majority of NZers will be getting vaccinated when it's available.

Without a vaccine you're cut off internationally.
Are any of those actually options "at the moment"? If I put a deposit on a Rivian or Cybertruck I have no idea when I would actually get to drive it, depends how many people are in line and whether their production lines ramp up on schedule. I can drive a Subaru off the lot today if I want.
Brave and Opera both use their own solutions for syncing.

In fact, can anyone name a browser except Chromium that uses Chrome's sync servers for syncing? Because I can't.

Also your point about backwards compatibility doesn't really make sense as Google has plenty of ways to detect browser version and capabilities of the sync engine (the sync engine sends that info to the sync server voluntarily right now).

Also Google can't just disable it's own API keys every time there is an update because this would shut down a large number of it's own users too. They would need to wait at least 1-3 months to avoid larger disruptions and this would give others more than enough time to fetch the latest keys (and if there is interest, there will always be someone who does that and posts them).

Well I reckon for 100M you could fabricate a chip at nearly any process size you want but probably not at a speed at which you could sell them for a profit. For example many universities have the capabilities to fabricate their own chips for research and development.

It also depends on what type of thing you're trying to fabricate. For example in a phone: cpu, ram, power, radio and sensors might want their own unique fabrication. It gets even more crazy when you want to go into things like automotive or industrial power.

I'll over generalize things and say that you can probably make a fab that goes down to 90nm without too much issue. It was the 65nm node when the lithography started to need something different and new chemistries were required for the fabrication process due to leakage becoming and issue that could no longer be ignored.

At least for me it was the jump to 65nm when I remember things getting hard and staying hard. The cell deigns had to change, the layout took twice as long, the models for simulations were always off and tapeing out to different fabs has vastly different results. It seemed like very node after that the documents that arrived from the fab about the new process were at least twice as thick as the last.
>all we have to keep things from breaking...ignoring them about something like a self driving car should be a criminal offense.

I think it would potentially be a manslaughter charge.
I agree with this concern. They collect a lot of data, sure, but they are also the only one who thinks that video is enough. It's a bold bet; intuitively, one would expect that video-only is good enough for gimmicks and fares worse when it comes to covering the millions of edge cases that still need to be addressed.
